Sparkill
Rockland and Putnam pools sit on higher bedrock with harder well water. Our protocol includes iron and manganese control, staged sequestrant addition, and DE-filter servicing adapted to local water.
Cyanuric acid (stabilizer) should stay between 30 and 50 ppm for outdoor pools. Over-stabilization is the most common reason chlorine "stops working." We monitor CYA quarterly and drain-dilute when corrective action is needed.
Typical weekly luxury pool service in Sparkill ranges $250–$600 per visit depending on pool size, water features, and service frequency.
